To all whomfit may concern.-

Be it known that I, J can ALEXANDER W11.- SON, aerated-water manufacturer, a subject of the Queen of GreatBritain, and a resident of Dundee, Scotland, have invented new and Boxes or Bearings of Carriages and other vehicles, (for which I have obtained Letters 1 Patent in Great Britain dated September 14, 1888, NO.'13,279,) of which the following is a specification, reference being had to the ac companying drawings.

This invention has for its object to provide a novel cup or cap for axle-boxes; and it consists in the features and combination of devices hereinafter described and clainicdjref crcnce being made to the accompanying drawings, in which- Figure 1 is a vertical longitudinal central sect-ion through the nave of a wheel, showing one form of axle box or hearing with my improvements applied thereto; Fig. 2 is a front elevation, and Fig. 3 a transverse section orrthe line 00 00,Fig. 2, both drawn to an enlarged scale, showing one form of my improved cup,

section; and Fig. 5 is a horizontal longitudinal central section on the line 1 y, Fig. 4, also drawnto an enlarged scale showing a device, hereinafter described, for keeping the glass clean. I

Like letters indicate corresponding parts. throughout the drawings.

A is the axle. B is the nave oi the Wheel. C is the box, bush, or hearing. 4

In axle boxes or bearings-such as that illustrated by Way of example in the accompanying drawings-the axle A has a collar it formed thereon or firmly attached thereto, and a loose collar h, adaptedto turn freely of bolts 0, which pass through holes in the said collar Z), and also through suit able holes provided in the said nave and in a second loose collar d. The bushor box G is secured in the nave ll by Wedges or other suitable means.

0. is my improved cup, cap, or cover, which has a screw-threaded portion 6' fitting into a correspondingly-scrcw-threadcd recess in the bush or box: 0. The front of the cup, cap, or

cover 9 is fitted with a disk or other suitablyshaped piece f of glass. or other transparent material, forming a window, through which the odor other lubricant in the axle box or hearing can be seen, so that the aniount'of lubricant in the said box' or hearing can at any time be conveniently and expeditiouslyascertained withouthaving to remove thsaid' cup, cap, or cover.

To insure tightness of thejointbetween the transparent piece fand the cup or cap eg'I employ cement orother suitable jointing material or packing.

The glass disk f in the app'aratus shown is secured in place by'turning over it the metal of the cup, cap, or cover 8, asat e g are leather or other washers for preventing the escape of the oil or other lubricant between the body of the axle box or bearing and the cup, cap, or cover 8.

'loavoid liability to breakage of or other injury to the transparent piece f, I provide a guard or shield 71, pivoted at h to the cup, cap, or cover a in such a manner thatwhen it is desired to inspect the axle box or hearing the said guard or shieldv h can be moved aside for that purpose.

In some instances I combine with my improved cup, cap, or cover means for auto matically cleaning the glass orother window, and t-huspreventing its being rendered opaque by the depositor accumulation of dirt or other substance so that the lubricant cannot be readily seen. For this purpose I prefer to provide a wiper 2', Figs. 4 and 5, made of leather, felt, or othersuitable material. 'his Wiper t is nxed ina spindlej, havinga square party" fitting in a co responding hole k in the end of the axle A. A spiral spring [is provided to insure the wiper being kept in con--. tact with the glass or other disk f.

The above-described wier beirv stationary and caused to bear against the revolving disk or window f will insure the latter being kept clean and free from any deposit that might otherwise obstruct the view.

It is obvious that I can somewhat modify the construction of my cup,cap, or cover without departing from the nature of my said in- ICO veniion. For example, instead of securing or pivoting the said guard or shield in the manner hcreinbeforc described, Ican provide the said guard or shield with a suitable hinge or other joint, so that it can be opened and closed.

I might make the cup cap, or cover entirely of glass.

Although I have described my said invention more particularly as applied to an axle box or hearing, wherein the wheel is retained upon the axle by means of a fixed collar on the said axle and a loose collar or collars bolted to the nave of the wheel, it is evident that my improved cup, cap, or cover is advantageously applicable to other axle boxes or bearings. For instance, by obvious modifications it can be applied to the axle boxes or bearings of railway-carriages or wagons, tramcars, and the like.

\Vhat- I claim is- 1. The combination, with an axle box or bearing, of the cup, cap, or cover formed wholly or partially of glass or other suit-able transparent material, and provided with a movable external protecting guard or ,shield on the outside of the cup, substantially asand for the purposes set forth.

2. The combination, with the cup, cap, or cover forined wholly or partially of glass or other suitable transparent materiahof means for automatically cleaning the said glass or other material,substantial y as and for the purpose set forth.

In testimony whereof I havehereun to signed my name in the presence of two subscribing witnesses.
